theZbot has some wonderfull ideas... duplicated here.
Hope that these things come true someday.

2. Blobs of paint
3. Boxed Objects
4. Thin Ice (this idea can be expanded)
5. One Use Reflectors
6. Unlimited Use Prisms
7. Smart Chompers (How smart?

)
8. Bonus Levels
9. Vertical or Horiziontal Reflectors (excellent idea)
10. Pushable Generators and Warp Gates
11. More Buttons and Teleporters (Don't we have enough?

)
12. Crumbling Walls
13. Doublecolor Gates
14. Stinker-only Floors (We may add Loof-only floors...)
15. Colored Steel Boxes
16. Arrow Shaped Buttons
17. LEVEL SETS
18. Super Trampolines
19. Link Cubes
20. Link Kegs
VirtLands would like to add:
21. Walls that crumble from cannon or laser blast.
22. Teleporters that only teleport objects, (NOT Stinky, Loof..)
23. Teleporters that only work if a wonderland coin (or $) is offered.
24. Gates that only work if a wonderland coin (or $) is offered (paid).
25. Rotten, mutant coins that when accessed take away regular coins.
26. Rotating reflectors (this idea can be expanded on).
27. The ability of Stinky to split into two Stinkies, (repeat with Loof...)
28. Shadow Creatures that copy your move exactly, not the mirror image routine.
29. A (toggling) Kaboom (or other monster) PAUSE button.
30. A Color-Changing Teleporter,... perhaps, after each
time you pass-over or use it, it changes to a different color and
therefore each time shall interact only with any matching
"teleport node" if any exists.

:idea:
31. A Traveling Teleporter, this one moves from square to square,
as if it had a mind of its own,... your challege is to catch up to
it if you ever wish to use it.
32. an "Earthquake button", that causes theZbot's "thin ice" to shatter.
33. Rainbow Boxes that change color with each move,
(according to some preset pattern), and each time two or more
boxes of the SAME current color meet, they vanish (into thin air).
34. Fusable Prisms, ... similar to "Unlimited Use Prisms", except that
after once used, they "weld" to the floor and can never be pushed
again, (in other words, cannon-fire makes them stick to the floor).
35. Rotating Light-spectrum Reflectors, (they don't physically rotate).
After each time a laser or canon blast hits this one it shall reflect
each cannon or laser blast as a different HUE of light, one blast
at a time, (in some preset pattern).
36. A Monster-Creation Teleporter, ...each time that you regretably
step on the "twin end" of this teleporter, a monster comes out
of that "other end", ( I've created a MONSTER~! Auugh! )
37. Multi-Dimensional Buttons, ...each time that you step on one
of these, the "some furniture" gets rearranged in the room you're in.
38. A Tri-Teleporter, ... (In Wonderland tri-teleporters currently
don't work right, this needs to be fixed.)
You're already familiar with the Duo-Teleporter.
A Tri-Teleporter is similar except that it has parts, A,B,C.
Some special pattern (or algorithm) must be created in order to define
the teleportation order for this tri-teleporter..
The suggested logic is: Each node teleports to the other node NOT last used.
39. A Quad-Teleporter, similar to a Tri-Teleporter... except more complex...
40. Please place your ideas here...
